Question

what is the name of the reaction when ethanoic acid is reacted with aluminum?

Answer 1

Hydrochloric acid is a strong acid and dissociates fully.

HCl → H+ + Cl-

This means that the concentration of H+ ions in 0.4 M HCl is higher than that in 0.4 M ethanoic acid, so its pH is lower and its acid reactions are faster. When alkalis are added, however, the ethanoic acid equilibrium position moves to the right, so eventually all the acid reacts, as shown in the equations below:

NaOH + HCl → NaCl + H2O

NaOH + CH3COOH → CH3COONa + H2O

Na2CO3 + 2HCl → 2NaCl + CO2 + H2O

Na2CO3 + 2CH3COOH → 2CH3COONa + CO2 + H2O

Mg + 2HCl → MgCl2 + H2

Mg + 2CH3COOH → (CH3COO)2Mg + H2

CuCO3 + 2HCl → CuCl2 + CO2 + H2O

CuCO3 + 2CH3COOH → (CH3COO)2 Cu + CO2 + H2O
